Re: Can an AC Installed make the engine run hotter than before?

If you're still asking if the A/C condenser adds heat, that answer is absolutely 1000% yes.

A condenser adds heat a couple ways.

1. It's physically blocking the radiator. Air still pulls through it, but not as easily as it did before the condenser was there.

2. Condensers can get pretty damn hot with the A/C cranked on high. So now, your fan is trying to cool your radiator and it's pulling the hot air through the condenser into the radiator as well, so the system has to work much harder.

That is why on any factory set up where A/C is involved, there is almost always a much larger radiator and a larger fan that pulls more air. That's probably not 100% true on modern cars anymore (can you even buy one without A/C?) only because it's cheaper to just put the "max cooling" stuff on everything, rather than have multiple parts for the same car (another reason why crank windows aren't offered anymore, it's actually cheaper to just have ALL cars have power.)


Post some pics of your current set up. Did you put the thermostat back in? That should be done before anything else.
